Found on my bathroom wall. It's v. young - 1.5 cm. Thought it may be a White Ermine, but it's not at all hairy and those patterns in the orange stripe don't fit. Camberwell beauty's got orange spots on its back (I've seen this look like an obstructed stripe on young ones) but there are no spikes and they don't really breed in the UK. It's probably something really common I've never heard of
